When you have a charger, data cable or power bank, you probably have these questions:
- Is the charger really outputting as much power as described?
- If the charger is not original, will it overcharging or overloading my cellphone?
- Is this cable good enough to deliver 1.5A or 2A I want?
- The power bank seems not that capacity as described, does it?
Now you have portable and easy use device to find the answers, moreover, you can test almost everything about electronics as long as they are using USB charging.
New Generation IC Used.
Used a new generation of power four semi- double loop integral converter IC, with a precision bandgap reference, range accuracy, high precision, stable and reliable
performance, strong anti- interference ability , high temperature can be used for measuring USB powered or power consumption of the interface, mobile phone
charger, U disk and other products.
This USB powered checker for good voltage and current as well as discharge (charging) will display in real time, and calculate the capacity (mAh).
displayed 500 mA x 0.25 H = 125 mAh (discharge capacity) and the so-called battery capacity in, for example, through the USB power supply checker, flow current 0.5 A for 15 minutes.
Displays and 500 mA x 0.5 H = 250 mAh, flow current 0.5 A for 30 minutes, 1 hour 500mA
could continue to be 500 mAh.
1 hour and a half if you can keep the sink 500mA × 1.5 H = 750 mAh, right?
Or until the charging rechargeable batteries become empty and charging through the USB power supply checker, how mAh charge capacity.
Also become mAh of discharge capacity at discharge or substantial performance in numbers can what to.
Mode switch button located on the right, long press, the mAh number as the value of the data number 0 record inside.
And, data number 0 is displayed: number 1 is set to new, mAh values to new measurement start from 0.
In this way, up to 10 data in it inside the record.
How to check the recorded data is as follows.
Double-click mode switching button the screen flashes and record data browsing mode, click the button in the State for each by you can make, view and record data in numerical order.
Double-click again to exit from the browsing mode.
Perch also flashes across the screen and exits read mode.
Outside no box package, will be delivered in the plastic bag, such as photos.
* No instruction manuals and accessories, is the only USB powered Checker body products. Please note that.
1. Can test the battery voltage, current, discharge capacity (total of 10 sets of data)
2. View: Double-click the button (0.5 S or less), enter to view the data view mode
3. high voltage or low Tip: LCD arrow LED backlight will flash alert notification
Note: When the voltage is lower than 4.7V on the instrument display or higher than 5.3V,the LCD screen will flash,Does not affect the use
Application examples
Because mobile phones and digital devices at low battery or full charge, the current and voltage is not a stable value, the application example of the discharge
device is a USB 1A or 2A discharge resistor.

Parameters that you can test:
Voltage of battery.
Current of battery, value of discharging capacitor.(Total ten parameters)
Communication function: Yes
Parameters adjusting function: Yes.
Equipment for parameters adjustment: One electronic load, one constant current source.
Voltage of constant current source should be set to 8.5V <vc< .="" be="" br="" cc="" constant="" current="" electronic="" load="" model="" proposal="" set="" should="" to="" style="margin: 0px; padding: 0px; box-sizing: border-box;"> There are 3A, 2A, 1A and 0.3A models for current adjusting.
Here is a example for 3A:
When you set electronic load at 3A model, the current will be adjusted step by step.
It will cost you about 10 seconds and you can see the result changing procedure in the LCD screen. When you see the 3A result shown in LCD screen, the adjustment process is finished.
You can shut off the electronic load and the parameters will be saved automatically.
Clean the data: Push the button until the parameters changed to next sets of parameters.
Then release the button.
Then the next sets of parameters will be
Started and they will start from zero.
Check the parameters: Quick beat the button double times(within 0.5s), then it is checking model.
The LED background will be flash.
Then you can see the
next set of parameters in LCD screen.
Quick beat the button double times again, you release the parameters checking model.
LED background be light with
flash.
Over voltage or under voltage: An arrowhead will be shown in LCD screen and LED background will flash.
Push the button and LED will be light without flash.
It will last 30s.
Turn on model.
The LCD screen will show all parameters within 1s when you connect power supply by Micro USB or male plug of USB with wire.(It is to check whether the LCD screen is good or not).
Then you can see the parameters used last time(capacitor and which set of parameters).
You also can see the current voltage,
current and over voltage or under voltage.
Please see following illustration.
USB output port can be connected to a data line, a discharge resistor or the like cable device comprising a data communication function, the data does not affect the data transmission line.
